SPECIFICATION forming part of Letters Patent No. 758,465, dated April26, 1904.

Application filed December 1, 1903. Serial No. 183,369. (No model.)

To all whom it mag concern:

Be it known that I, ERNST ORTWEIN, a sub-' No. 2 Oberes-Rheinufer,Ludwigshafen-om the-Rhine, Germany, have invented a certain new anduseful Improved Horizontal Water- Wheel; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

This invention has for its subject-matter a water-wheel rotating with avertical spindle and provided with hinged blades which automaticallylift out of the water when returning against the stream.

In the accompanying drawings, Figure 1 is Fig. 2 is a longitudinalsection.

Mounted in the foundation f is a foot-step carrying the main spindle a.Fitting on the lower part of the main spindle is a sleeve Z).

Immediately on the foundation-plate d is a divided disk 0, which takesinto an annular slot in a tooth-wheel g, so as to permit a rotation ofthe latter while preventing it rising.

Secured to the enlarged and strengthened head of the sleeve 7) is acarrier-plate lb, which is divided, -so as to enable it to take into anannular slot in the nave i of the water-wheel, so as to allow it tofreely rotate, While at the same time preventing it lifting from thecar'- rier-plate. Ball-bearings are provided to diminish friction. Onthe carrier-plate is a cam ring or path t, somewhat longer than asemicircle and having inclines at each end. On the nave z is secured abearing-plate Z, to which the blades or paddles 7c are hinged. Eachblade is provided with a supporting and running bowl m, mounted inball-bearings. As the wheel revolves these bowls run up the inclines ofthe cam-ring, along the raised path, and down the end inclines, thustilting up the blades as they return against the stream. Thebearing-plate Z and the nave e' engage, by means of a feather or key, ina longitudinal slot in the spindle a, so that the rotation of the bladesis imparts rotary motion to the spindle a, which may be applied to anyuseful purpose. The upper end of the spindle a is carried in a bearingin girders 0, secured to pillars n. In order to adjust the height of theblades to varying water-levels, the tooth-wheel g is preferablyconstructed as a worm-wheel to be rotated by the Worm p. The wheel g isinternally screwed and engages with a screwthread on the outside of thesleeve 5 for the purpose of elevating or depressing the whole wheel.

The lower part of the sleeve 6 has a longitudinal slot, into which takesa feather or key a", screwed to the foundation-plate all, so as toprevent the rotation of the sleeve 6. The shaft 8 of the'worm may beprolonged and carried to any convenient position, whence it may beoperated. In some cases it may be connected, by means of a clutch or thelike, with mechanism deriving its rotation from the main spindle a, sothat the power of the latter might be used when required to elevate ordepress the wheel.

-What I claim as my invention, and desire to secure by Letters Patent,is-' The combination with a vertical spindle a of the sleeve 5, theworm-wheel g, the worm p, the carrier-plate h, the cam-path t, the nave'5, plate Z secured thereto and the blades is hinged to the plate andhaving carrier-bowls we bearing on the carrier-plate h and the cam-pathat substantially as and for the purpose set forth.

In witness whereof I have hereunto set my hand in the presence of twowitnesses.

ERNST ORTWEIN.
